Frequently Asked Questions (FAQ)
Seamless tubes are manufactured from a solid billet of steel that is heated and extruded through a die to form a hollow tube. This process creates a product with no weld seam, providing superior strength and uniformity compared to welded tubes, which are formed by rolling a flat sheet of metal and welding the edges together.
For standard sizes, our typical lead time is 7-14 days. Custom orders with specific dimensions or special requirements may take longer, typically 15-30 days depending on the complexity of the order and current production schedule.
Our stainless steel tubes comply with various international standards including ISO 9001, ISO 14001, API, ASTM, ASME, and PED. We can provide material test certificates (MTC) and other documentation as required.
Yes, we can provide samples for testing purposes. Please contact our sales team to discuss your specific requirements and arrange for sample tubes.
